We’ve all seen the movies where a lock is poked around with a hairpin and the door miraculously opens. But how realistic is this?

This tutorial video by NightHawkInLight shows how you can simply open a conventional key lock with nothing more than two hairpins. The guide uses a transparent lock in this video to demonstrate the mechanism of the lock pins and how to work around them. The video makes the task look deceptively, if not worryingly, easy. But remember: without the see-through lock, you'll essentially be doing it blindfolded, instead relying on just your ears and sense of touch.

Check out the video below. Just don’t go using your newfound powers on other people’s locks, otherwise you’ll probably have a hard time explaining that you're not trying to rob the place.
